Principles and practice of operative dentistry . Inferior right first and second molar, cow-horn forceps. rocking movement until the tooth is loosened in its alveolus, when thetooth should be removed by traction upward.

When the root, however, is straight, their extraction is a verysimple matter by the use of bayonet-shaped forceps having simple beaksmade to fit the convexity of the root upon the buccal and lingual 695 shows such an instrument designed for use upon either the right Fig. Bayonet-shaped superior third molar forceps (universal). or the left side of the mouth. The positions of the patient and theoperator and tlie application of force are the same as for the extraction ofthe other superior molar teeth. Sometimes these teeth are large and havebifurcated roots. Under such circumstances the ordinary superior molarforceps should be employed for their extraction. EXTEACTIOX OF TEETH. 689 When the roots of these teeth curve backward the ordinary forcepsused for the extraction of the third molars will not dislodge them. Specialforceps are then called into use. To meet these requirements the late DrPhysick invented the forceps shown in Fig. 696. The jaws of this instrument represent two inclined planes looking towards each other. The in-strument is designed to act as a double wedge when placed between two Fig. 696.
